Abstract
A procedure based on liquid liquid extraction(LLE)-GC/MS has been developed for the simultaneous analysis of antioxidants and insecticides known as endocrine disrupters. The endocrine disrupters investigated in this study are butylated hydroxy anisole(BHA) and butylated hydroxy toluene(BHT), and the insecticides are allethrin and fenvalerate. The limit of detection(LOD) was 0.071~0.159 ng/ml with RSD of 1.41~5.34% for the standard sample. From water reservior of Han river, Geum river, Nakdong river and Sumjin river, these compounds were not detected. For the synthesized sample, the LOD is 0.051~0.132 ng/ml with RSD of 6.39~13.4%.
